A heart drug digitalis is derived from which plant?

Explanation:
Digitalis comes from foxglove plants. The heart drug is a cardiac glycoside found in Digitalis species (like Digitalis purpurea), which increases the heart’s pumping force by inhibiting the Na+/K+ ATPase pump in heart cells, leading to higher intracellular calcium and stronger contractions. This traditional source is why the drug is named digitalis. Other plants mentioned are associated with different drugs—willow with salicylates (aspirin), poppy with opioid analgesics, and mint with menthol—not with digitalis.
